vide a hoist ot this kind which will coin-- bine strength and rigidity with lightness, so that it may serve for lifting comparatively heavy loads, and may at thesame time be easily handled `and readily placed in and removed from its operative position.

Another Objectis to provide a portable hoist which will enable a receptacle to be raised `from a well to the level of the ground or Hoor by means of a windlass, and will then admit of being bodily moved or rotated to a position out of line with the'well for the purpose of depositing the receptacle' on the floor with ,slight exertion on the part of the operator. To this end my improved hoist is preferably constructed of light pipe material, bent up to form two substantially parallel legs, spaced apart suiiiciently to straddle the well, one of the legs beingl'onger than the other and adapted to enter a vertical socket provided-in a frame surrounding the well, and the other leg carrying a Vcaster or bearing roller, adapted to travel on the floor about the socket as a center whereby when the receptacle is drawn up t0 a position slightly above the floor level the apparatus may be Vhorizontally rotated and the receptacle thus-lowered to an accessible position on the floor.

A further object of the invention is to provide a device of this character which may be cheaply and economically manufactured, consisting of few simple and durable parts, and which will withstand rough usage without danger of impairment or disorder.

Another object of the invention is to `provide an improved portable hoist which when not in use may be conveniently hung on a nail or peg oni-the -wall where it will be safely out of the way and will not'encumber ther-floor.

With the above and other objects in view the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings, Figure l represents a view in elevation of my improved hoist showing the same in operative position over an ash well; and Fig. 2 represents a plan view theerof showing in dotted lines, the positionof the device when the receptacle is swung to the floor adjacent the well.

Referring more particularly to the drawings, A represents a well or pit in a lawn or cellar, B represents a frame surrounding the mouth thereof, and C' an ash or garbage receptacle adapted to be wholly contained in the well and introduced therein and withdrawn therefrom through the frame. A removable closure (not shown) is provided for covering the well, and is adapted to enterV the frame and be seated on an internal flange 3 thereof, the frame and the closure being so constructed as to rest flush with the adjacent fioor surface.

D designates the body of my improved hoist which is constructed in the form illustrated with two substantially parallel leg members` l and 5 spaced apart a sui'licicnt distance to straddle the well and rigidly connected at-their upper extremities by a bridge member 6; wherein is centrally mounted a windlass `7. Preferably the entire body of the hoist including the leg members and the bridge member 6 is madeoi` one continuousl length of light cylindrical pipe material bent upon anappropriate; form, although I may likewise make the same in separate and suitably connected 'parts Leg member 4 is somewhat greater in length than leg memberv and is designed to enter and snugly rotate ina vertical socket 9 formed in the wellfra1ne,-said socket being` of suiiicient depth tof substantially support the hoist in a vertical position over the well. Leg member 5 is provided at its lower extremity with a bearing roller l() mounted for rotation in a direction at right angles to the plane common to the leg members, and said roller. when the hoist is in operative position, is adapted to `rest upon and travel over the upper surface of the well frame and the adjacent Hoonfollowing an arcuate path having the-socket 9 as its cent-e r.

Theevindlass 7 is preferably mounted in a simple manner in an upwardly projecting inverted U shaped extension Q2 of the bridge member (i, a shaft l2, carrying a rigidly attached drum 123 haring end flanges ll, being journaled in suitable perforations formed in opposite vertical arms 2() and 2l of said eX- tension, said shaft continuing outwardly bevoud the leg l and terminating in a hand crank 1G, within easy reach of the operator. A cable l5 carrying a hook 17 for engaging a bail as 18 provided adjacent the top of the receptacle C, is secured to the drum and winds thereon to raise or lower the reeepv tar-le when the shaft is rotated.

1t will be noted that the leg members fl and 5 are made ot' sutlieieut length to permit the receptacle which may be of any desired type to be retained in i'ree suspension between the bridge member and the floor when the hoist turned to the side of the well; and further that the socket 9 is provided with a bottom piece or internal rabbet Q2 whereon the leg member il is adapted to rest.

1n the operation of my improved hoist, it will be apparent, that when the receptacle is hoisted out of the well and raised to a suf-li` cient height to clear the tioor, the operator, without diseugaging his hold on the crank handle, may, with slight exertion, turn the hoist bodily about the socket to one side of the well, and thus move the receptacle to a position out of line with the Well shaft where it may be lowered firmly upon the door, as shown b v the dotted lines in Fig. 2.

Then the hoist is not in use, it may be conveniently hung on the wall by passing the upper part of the U shaped extension 22 over a peg or nail driven at a suitable height.

While I have shown and described the preferred embodiment of my invention, it is understood that the same is susceptible of modification in various particulars without departing from the spirit and scope thereof or sacrificing any of its advantages.

lVhat I claim is:

1. A hoist adapted to be rotatively mounted over a Well for removing an ash or garbage receptacle therefrom, said hoist comprising two substantially parallel leg members connected at their upper ends by a bridge member wherein a Windlass is mounted, one of said leg members being longer than. the other and adapted to enter a socket adjacent one side of the well, and the other leg member carrying a bearing roller adapted to travel on the Hoor surface surrounding the well.

i2. A portable hoist adapted to be removably and rotatively mounted over a well for removing an ash or garbage receptacle therefrom, said hoist comprising two substantially parallel leg members connected at their upper ends by a bridge member wherein a windlass is mounted, one of said leg members being longer than the other and adapted to enter a vertical socket formed in a frame disposed about the mouth of the well, and the other leg member carrying at its lower extremity a bearing roller adapted to travel on the upper surface of the frame and the surrounding {ioor about the lower leg member as a pivot.

3. A portable hoist for removing an ash or garbage receptacle from a well, comprising two substantially parallel legs spaced apart to straddle the well, a bridge member connecting said leg members at their upper ends and a windlass mounted in said bridge member, one of said leg members being of greater length than the other, and the shorter leg member carrying a bearing roller, mounted to rotate in a direction at right angles to the plane common to both leg members.

4. A portable hoist for removing an ash or garbage receptacle from a Well, comprising two substantially parallel leg members spaced apart to straddle the well, a bridge member connecting said leg members at their upper ends, a Windlass mounted in said bridge member, a bearing roller carried on the lower end of one of said leg members, and means provided on the other leg member for removably supporting and revolubly pivoting the hoist in an upright position over the well.

5. A portable hoist having two substantially parallel leg members, a bridge member connecting said leg members at their upper ends, a windlass mounted in said bridge member having a shaft extending outwardly beyond one of said leg members and terminating in a crank, means for removably supporting and pivoting said hoist by one leg member and for bodily rotating the hoist When so pivoted on the other leg member.

6. A portable hoist bent up of one continuous length of pipe material, comprising two substantially parallel leg members, one leg member being of greater length than the other, and the shorter leg member carrying a bearing roller at its lower end, a bridge member extending between said leg members at their upper ends having an upwardly projecting inverted U shaped eXtension formed therein, and a windlass mounted between the vertical arms of said extension.

7. A portable hoist bent up of one continuous length of pipe material, comprising two substantially parallel leg members, a bridge member extending between and connecting said leg members at their upper ends, an inverted U shaped upwardly eX- tending projection formed in said bridge member, a windlass mounted in said projection and journaled in the opposite side arms thereof, and a sulicient space provided between said windlass and the upper portion of said extension for the reception of a nail or peg, whereby the hoist when not in operation may be hung away in a vertical position.

8. In combination with a horizontal supporting surface having a Vertical socket therein, a portable hoist comprising two substantially parallel leg members suitably oonnected at their upper ends, one of said leg members being of greater length than the other and adapted to enter the socket to support the hoist in an upright position on said supporting surface and to act as a pivot for the rotation of the hoist about the socket, and the other leg member carrying at its lower end a bearing roller adapted to travel on ,said supporting surface.

9. In combination with a circular horizontal track surface surrounding a vertical socket, a portable hoist comprising two substantially parallel leg members rigidly oonnected at their upper ends by a bridge niember having a Windlass mounted therein, one of said leg members being longer than the other and adapted to enter said socket to support the hoist in an upright position over said track surface and to aet as a pivot for bodily rotating the hoist about the socket, and the other member carrying a bearing roller at its lower end, said bearing roller being adapted to travel on said track surface.
